TYIPEWRITING-MACHINE.

Specification of Letters Patent.

Patented Jan. 4, 1921.

Application led January 17, 1918. Serial No. 212,215.

To all whom t 'may concern:

Be it known that I, BURNHAM C. Srroii- NEY, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Typewriting-Machines, of which the following is a specification.

This invention relates to tabulating devices for the carriages of typewriting machines, and particularly to means for selectvely bringing into use different sets of column-stops.

In the patent to McLaughlin No. 941,166

, of November 23, 1909, the column-stops are arranged at certain letter-space intervals on the typewriter carriage. These 'columnstops are normally out of working positions, but by means of a special mechanism different sets of stops may be projected to working positions at will. Each of the column-stops is pro-vided with a lug or shoulder, and along the row of shoulders extends a revoluble shaft, having thereon different sets of tappets for engagement with corresponding shoulders of the column-stops, so that by rotating said shaft to different positions, corresponding sets of column-stops will be projected from idle to working positions. The tappets are made in different forms, and are adjustable to different letter-space positions along the shaft, so that any desired combination of tappets may be made up.

ne of the object-s of the present invention is to increase the capacity of a stopsetting mechanism of this nature. Vhile the invention may be carried out in numerous f orms, still for the sake of convenience it is illustrated in connection with the form of tabulating mechanism which is disclosed in said Letters Patent. v

In carrying out the invention, provision is made for substantively increasing 'the number of tappets, whereby the columnstops may be projected, so that the capacity of the machine is increased, and many more settings or combinations of stops are permitted.

Instead of providingr each column-stop with a single shoulder or lug, as in said Letters Patent, I provide it with two or more such stop-setting elements, thus forming two or more rows of shoulders extending along the carriage; and for each such row of shoulders I provide a separate multiple stop-setting device in the form of a rotatable shaft having thereon stop-setting elements or tappets for engaging the shoulders to set the stops. These shafts may be placed one behindthe other, and the tappets thereon may be so arranged that any stop may be operated by either rock shaft without collision with any tappet upon the other rock shaft. The tappets on each shaft may be formed in single, double, triple or other multiple form, as parts of stop-setting members which may be adjusted along the shaft and secured thereto in the Inanner set forth in ,said Letters Patent; and each shaft may be provided with a fingerpiece for rotating the same independently of the other'shaft,and with means for holding it where set. Each shaft-'is also preferably provided with indicating means to designate its different stop-setting positions, said means comprising an index and a scale, the scale on the first shaft, for example, being provided with the numbers l to il, and that upon the second shaft with the numbers 5 to ,9; any additional shafts being given higher numbers, so that when desiring to use any particular setting of the column-stops, the operator will turn the proper shaft until the corresponding number thereon is opposite its index. While I have illustrated one shaft as capable of making four different settings of the column-stops, and another shaft as capable of making live other different settings of stops, still it will be understood that each shaft may be capable of making either less or more settings, and an desired plurality of shafts may be used.r If, however, only two shafts are used, other settings, in addition to those which are made by each shaft individually, may be had in some cases by the combined use of said shafts in their different positions, in which case the indicating means of the` two devices may be used to give combination indications representative of all the differentcombination stop-settings which may be effected by the two devices when used conjointly.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Fig. 7 is an end elevation of the parts seen in Fig. 6.

Fig. 8 is a side view, somewhat diagrammatic, showing the principal parts of the tabulating mechanism.

rlhe column-stops 10 are shown arranged in a row upon a letter-feeding typewriter carriage 11, usual intheUndcrwood typewriting machine, and out of positions for coperating with the usual decimal-stops 12 which` are projected by the usual tabulator keys 13. l

Each column-stop 10 has two ormore stopsetting elements herein disclosed as lugs or shoulders 14 and 15 which are in'position to be engaged by spurs, tappets, or other stopsetting elements 16 and 17 Vcarried upon rotatable shafts 18 and 19, respectively, which extend horizontally across themachine parallel with the rows of Vshoulders or lugs. The shafts have finger-pieces 2O and 21, whereby they may be rotated, and detent wheels 22 and 23 having spring-checks 24 and 25 whereby they will be held in position. If desired, each check may be provided .with a linger-piece for withdrawing it from the notches in the detent wheels.

The spurs may be formed upon separate stop-setting members herein disclosedl as collars 26 and 26"L adj ustably connectible to said shafts 18 and 19 by means of lugs 27, as set forth in said Letters Patent, and each collar may have from one to five or more spurs thereon. In the drawings, the forward shaft 18 is illustrated with collars 26 having as many as four spurs 16, while the rearv shaft has collars 262L provided with Afrom Vone to five spurs 17. By setting a variety of collars or adjustable devices 26 and 26a ina variety of places alongthe shafts, provision maybe made for projecting any desired arrangement of column-stops and for shifting the arrangement when desired, by merely rotating the shaft 1S or 19, orboth shafts, as will hereinafter appear.

The lugs 14 and 15 are'arranged one behind the other and the spurs 16 and 17, on the forward and rear shafts, respectively, for operating said lugs, are arranged in the same plane with the column-stop 10. The column-stops may be set by either the front shaft or therear shaft, because in either case the lug which is out of use does not collide with the spur upon its associated shaft; suitable clearance being provided for avoiding such collision. In other words, the same column-stops may be set by either shaft Vindependently'of the other shaft. Thus, for example, a single column-stop may be capable of setting-by four spurs upon the forward shaft a-ndve spurs upon the rearward shaft, so that said stop will `be set to any position to which either shaft may be turned, and obviously the same columnestop-m'aybe settable by more than nine spurs. Thus, a wider range of the capacity ofthe `machine is secured, and the range maybe increased vby increasing the number of spurs upon the shaft, or by increasing the number of shafts, or bythe 'adoption of bothl expedients.

rThe column-stop blades are madelonger than those disclosed in saidfpatent, so asto afford room for the additional lugs'thereon; each column-stop blade being guided in a rear rack 28,'and also-by slots in'the :front rack 29, substantially asset forth in said Letters Patent; and each being also pro- Videdwith a vretracting spring`30-to return the stop to normally ineffective fposition, whenever,in the rotation of the" active shaft, a shaft-spur escapes from the stop-lug; said shaft-spurs being formed'to hold the lugs projected vby the "aid of the .spring-checks 2i, 25.

Scales 31 and 32'areprovided to 4position the shafts 18 land19, respectively. The scales have indicators '33 and "34 associated therewith to ,assistinf'selecting the vvarious arrangements of stops which correspond to numerals l to 4 on the'bar18,and 5 to 9 on the bar'19. rhesescales are preferably 'arranged on the 4finger-wheels 2O land 21, and the numbers thereon may denote various positions to which the setting shafts may be rotated to selectively move the column-stops totheir working'positions in different arrangements; these arrangements of the stops corresponding-'to different forms of work which'mayE betyped byi the machine.

It should be understood" that some of the column-stops may'havey onlyY one adjustable collar or device having ithe tappets associatedwith said column-stops,-and that vsaid collars maybe distributed on both-setting shafts. It will be seen that with this arrangement ofradjustable collars adjusted on a plurality of manually-'controlled shafts, there canbehad, in addition to those group settings or set arrangements of 'column-stops corresponding `with numerals `upon Athe finger-wheels 20 4and j21, certain other group stops of said series in different combinations, including settings differing from those which may be effected by the other, the relation betvveen said stops and the members and elements of said setting devices being such that said devices may be operated concomitantly to effect a plurality of predetermined group settings of said stops, in various combinations differing from those Which may be effected by either device alone.

combination tabulating mechanism comprising, in combination, a single series of settable tabulating stops, and a plurality of selective multiple-stop-setting devices, each capable of concomitantly effecting different predetermined group settings of stops of said series, and also capable of conjoint use to effect various combination settings of stops of said series, each of said setting devices being provided with indicating means to designate its different stop-setting posi tions, said indicating means of the tivo devices being capable of giving combination indications representative of all the different combination stop-settings which may be effected by the two devices when used conjointly.

b'. The combination with a carriage, of a set of column-stops, tabulator stop, and a plurality of setting devices, each capable of independent operation to set different groups of stops of said set to effective Working positions, the stops of each group being set concomitantly, each of said column-stops having a plurality of setting shoulders or parts, to enable it to be set by either of said setting devices as one of a. number of stops selected for a predetermined group-setting.

T. tabulating mechanism comprising, in combination, 'a series of column-stops, each movable from a normal position to a set position, resilient stop-restoring means tending to restore said stops, When set, to their normal positions, a plurality of rotatable multiple-stop-setting devices, each capable of being turned, by a series of partial rotations, through a plurality of neutral and effective stop-setting positions in alternation, each of said devices having a plurality of stop-setting elements, different groups of which may be caused to concomitantly and selectively engage and set different predetermined groups of said stops on movement of said setting device through its different stop-setting positions, and means for maintaining each of said setting devices in any of its neutral positions, and for also maintaining' it in any of its stop-setting positions, so as to maintain the corresponding group of stops, set thereby, in their set positions, against the counteracting influence of said stop-restoring means, the relation between said stop-setting devices being such that neither device, when in its neutral position,

will interfere with the setting of any of said stops by the other.

8. In a typewriter, in combination, a carriage, a support therefor, a tabulator-stop mountedin one of said parts, a set of column-stops mounted in the other of said parts, -a selective multiple-stopsetting devicevcapable of setting a plurality of predetermined stops of vsaid set concomitantly, and a second selective multiple stopsetting devicel capable of effecting settings of adifferent plurality of predetermined stops Vof said set concomitantly, said setting devices being capable of being used conjointly, as Well as singly', so as to be capable of'selectively effecting combination settings of said stops different from and greater than those which may be effected by either setting device alone.

9. In a'typewriting machine, in combination, a carriage, =a supporttherefor, a 'tabulater-stop mounted in one 'of said parts, a

set of column-*stops mounted in the other of' saidparts, and a plurality of selective multiple-stop-setting devices for saidcolumnstops, each of said devices comprising stopsetting elements in setting relation respectively with different column-stops of said set, certain of said stop-setting elements l'iaving a plurality of stop-engaging-members, the differentk members of each'elementybeing capable of being caused to set'the same stop aiplurality of times in succession as a'- yresult of a succession of operations of the stop-setting device of which it is an element, the stop-setting elements of the same setting device including elementsfdiffering from each other as to theirl respective numbers ofstopengaging members, 'said stop-setting devices being capablefof independentoperation to selectively effect variable group v4settings of column-stops of said set,.the stops `of each group beingy set concomitantly.

,10. In a` typewriting machine, in combination, a carriage, a support therefor, atabulator-stopfmounted in 'one of said parts, a set of column-stops mounted in the other of said parts, and a plurality'ofselective multiple-stop-setting devices for said columnstops, said devices comprising stop-setting elements in setting relation with columnstops of said set, the stop-setting elements of one of said devices beingindependently settaole at varying positions with respect thereto, so as to be capable of being selectively caused .to be brought'into stop-setting relation with different column-stops of said set, said stop-setting devices being capable of independent operation to selectively effect different group settings of columnestops of said set, the vstops of each group being set concomitantly.

'11. In a typevvriting machine, in combination, a carriage, a vsupport therefor, aitabusettings or arrangements for which a setting of both shafts is required, thus increasing the range of capacity of the machine with any additional shafts or tappets; as, for example, the shaft 18 may be set to 1. If the shaft 19 is at the same time set at 4,7 a set arrangement is had, which diers from any of the arrangements of the stops set up by any individual shaft. 1f the shaft 18 is left in its 1 position and the shaft 19 rotated to its 5 position, still another arrangement is had. In this way many other arrangements of stops may be had. It may be observed that the indexing means of the two setting devices, when used conjointly, may be regarded as a combination indexing means capable of givingindications representative of all the different combination settings which may be effected thereby. In the two examples just given the first setting would be designated as number 14 and the second as number 15.

llVhen one of the setting shafts is to beused alone, the other shaft is first moved to a neutral position, to render the tappets ineffective, by rotating it until a dash between the numerals on the scale of the finger-piece comes opposite the corresponding pointer.

The spring-checks 24 and 25 may comprise pawls 35 and 36 coperating with the toothed wheels 22 and 23 on the setting shafts 18 and 19, respectively. These pawls prevent the backward rotation of their respective shafts, which the springs 30 have a tendency to cause through the intermediary of the column-stops 10. It will be seen that the teeth on the wheels 22 and 23 are so shaped that the setting shafts 18 and 19 may be rotated, in the opposite direction, to set the stops 10.

The pawls 35 and 86 may be shaped to fit between the teeth of the wheels 22 and 23, so as to yieldingly hold the setting bars, to prevent accidental displacement thereof from a neutral position, which may be caused by the jarring of the machine.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, l claim:
